A method for recovering a liquid substance such as fuel oil from ships sunk or stranded due to marine accidents and from storage facilities by more easily heating the liquid substance to reduce its viscosity, and a device for recovering liquid substance. A working coil (2) is applied to the inner bottom plate (7) of a conductive tank (6) in contact with the liquid substance to be recovered, a high-frequency current is supplied to the working coil (2) from a high-frequency inverter unit (3) to heat the inner bottom plate (7) itself by induction heating and the liquid substance is reduced in viscosity by the heating for recovery via a recovery pipe (5) connected to a pump (4). Therefore, an object to be heated can be heated in contact with a heat source and efficiently without an intermediate heat loss, no bulky steam boiler nor large occupied space is required for ease of handling and working, manpower and working hours can be significantly reduced, a quick measure can be taken when a marine accident occurs, and an effect of weather is more likely to be avoided.

1. A method for recovering a liquid substance by applying a working coil to a liquid substance contacting member which is a member of a tank containing the liquid substance is in contact with the liquid substance containing in it or flowing through it and is made of an electric conductor, supplying a high-frequency current from a high-frequency inverter unit to the working coil to cause the liquid substance contacting member itself to generate heat by induction heating and thereby reducing viscosity of the liquid substance, and recovering this liquid substance through a recovery pipe connected to a pump.
